There are a few reasons why washing your hair too much could be troublesome. Honestly, if your hair tends to be very oily, you don’t color it, and you don’t heat style, then washing your hair daily should be completely fine for you, but if you tend to have dry hair, you color it, or you heat style after every shampoo, then washing it daily can just add to the dryness of your hair. Too much heat, is just plain and simple, too much heat. Your water can be another problem. If you live in an area with hard water, over washing is going to eventually take its toll on your hair. In this case, I recommend a water filter on your shower head, only washing every few days, and detoxifying treatments at your favorite salon once in a while to remove buildup. If you’re using the wrong products for your hair type, and you’re washing too much, this also can cause dryness. I always recommend professional brand hair products. I promise, your hair will thank you!
